The 4063 are low-DC mics needing only 3V instead of 5V(DPA4060/61/62).
http://dpamicrophones.com/module.php?MID=101&itemid=4063-BM&PID=&function=pdescriptionThey should work fine with plugin-power of your Edirol R-09.
I heard recordings of 4061´s(5V minimum) with plugin-power(2-3V)....it´s possible but sounds strange.
You need to do the microdot=>3.5mm(1/8")-plug-mod as these babies come with microdots(DPA sepcific termination).

There are extremely small 12V-battery-boxes available at soundprofessionals.com. Consider using 3.5mm-modded-DPA4061´s in combination with a miniature 12V battery-box..smaller than a car remote(mine at least).
